I made this life-size model of chicken by modifying original tyrannosaur and it features: moving legs, wings, neck and head with opening beak. Chicken is built only out of tyrannosaur's parts so you don't have to take apart Jurassic Park gate. You can also build little dinosaur from leftover parts. Building instructions can be bought exclusively from rebrickable.com where you will be redirected after clicking on "Download instructions".

Simple model of dinosaur built out of parts that leftover after finishing model of chicken.
